Slow Loading Collapse/Show Tabs

[Peter]

Hi,

I have a radtabstrip (within a documentpanel) the tabstrip has about 20 tabs, each tab contains either a datagridview or a tablelayoutpanel with several controls in it (about 30 textboxes/labels). i want to dynamically change the visibility of the tabs, when i click a certain node in a treeview, the right tabs should be shown/hidden.

so i check which tabs are already visible and hide them as following:

public void hideTabs()
{
    foreach (TabItem ti in radTabStripMain.Items)
    {
        if (ti.Visibility == Telerik.WinControls.ElementVisibility.Visible)
        {
            ti.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
        }
    }
}

and in my selected event of the treeview i've put:

private void rtvImmo_Selected(object sender, EventArgs e)
{
    hideTabs();
    switch (rtvImmo.SelectedNode.Level)
    {
        case 0:
            tiPatrimonium.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            tiPatrimoniumLasten.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            tiPatrimoniumVerzekeringen.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            radTabStripMain.SelectedTab = tiPatrimonium;
...

However, this takes ages to load the new tabs to be shown?

any help would be appreciated!

Regards,

Peter
